ROLLER POR SKATES.

APPLIGATION FILED JUNE 5. 1905.

Ira/em wax- UNTER?" STATES To all whom it may concern.'

Be it known that I, Oris W. EvERE'r'r, a citizen of the United States, residing at Worces ter, in the county of Worcester' and State of y Massachusetts, have invented certain new and useful Im rovements in Rollers for Skates, of which t e following is a specification.

My invention relates to a roller or Wheel,

and particularly to a metal roller or wheel for 1o roller-skates.

The object of my invention is to make a metal roller or wheel, preferably of steel and having ball-bearings, of improved construction and in which the several parts of the roller are first pressed or formed into the desired shape and then put together and permanently secured together to make the completed roller without any rivets or screws.

My invention consists in certain novel features of construction of my im rovements, as will be hereinafter fully descri ed.

I haveshown in the drawings'a roller or wheel of my im roved construction cornbined with an ax e and a truck of a rollerskate of ordinary and well-known construe-l tion.

Referring to the drawings, Figure 1 shows a skate-truck, an axle, and a roller of my improved construction. Fig. 2 is a central vertical section through my improved roller and also shows the ax e attached at one end to the roller. Fig. 3 shows the several parts of roller detached. Fig. 4 is a front side #View of a ballfcup shown in Fig. 3 looking in l 1 the Ydirection of arrow a, same ure. Fig. 5 y is a front view of the ball-cup ho der shown in 3 looking in the direction of arrow b, same figure. Fig. 6 is a side view of the roller tire or rim shown'in Fig. 3 looking in the direction of arrow c, same figure.

In the accompanying drawings, 1 is a metal roller-skate truck, which may be of an usual and well-known construction and whic is se cured to the skate (not shown) and has a bearin for the axle 2 in the usual way.

I wi l now describe m improved roller.

My improved rollerLwiiichismade of metal and preferably of steel, comprises the tire or rim 3 of suitable width and flat throu hout its width and formin the flat tread or earing surface of the rol er. The rim 3 has one edge turned over or bent downwardly, forming an inwardly-extending annular lip or Specification of Letters Patent.

which a e sed or formed into the shape, shown in' t e drawingw-lh' the annular lpe-v ripheral li or flange portion. 4 extending 'atEA right ang es to thev main- `ortionand of --awidth a little less than onealf the width'of i i the rim 3 and adapted tov fit tightly'w'vithinE 6o the rim 3 and the centralfhub portion l4"-- adapted to receive the ball-cup 5. The por# tion of the cupholder 4 intermediate theflr'imj A I i portion 4 and the hub portion 4'. is/prefe'r'; fably perforated or'provided with' openings 65 4', as shown in Fig. 5. The ball-cup 5 has',

`preferably, an outwardly-extending lip' orf' l flange 5/ on its outer edge, which is cut away at one point, 5, as shown in Fig. 3.

In assembling the parts (shown: in Figi-3)l of my improved roller one of the ball-cup holders 4 is placed within the rimA 3 and forced therein until the outer edge bears4 against the lip or flan e 3.

ortion 4 is then lace p within the rim 3 and orced against t e first cup portion. The' ledge of the rim 3 opposite to the flanged edge lf3 is then turned over or pressed downward y and inwardly, as shown at 3, Fig. 2, to hold the two cup portions 4 within the rim 3. Each ball-cu 5 is then inserted and forced within the hu ,portion 4 of each cup-h`6ll 4, 'aiidaportion of th-e hub portion 4" is bent into the notch or recess 5 in the annular lip or flange 5 on the ball-cup 5, as shown at 4 in Fig. 2. In this manner the several parts of my improved roller are rigidly and firmly secured together without the use of any rivets or screws. After the several parts of my improved roller have been put to ether thev The other cup i com leted roller is placed upon t e axle 2, g

and alls 6 are and the adjustaiile cone 7 is screwed onto the threaded end of the axle 2. A cap 8 is placed on the axle 2 and fitted over the outer end of the cup-holder 5, a washer 9 is fitted onto the axle, and a nut 10 screwed on to secure the parts together in the ordinary way.

The advantages of my improvements in roller or wheel will be readily appreciated by those skilled in the art.

I provide agnetal roller or wheel having a flat tread or earing-surface of ve strong and durable construction and in w 'ch the several parts are permanently and rigidly secured together without any rivets or screws.

t will be understood that the several parts -lange 3. `.There are two ball-cup holders 4 Q-girly roller or wheel are made of such a size ...wml

laced within the ball-cup 5,

IOO

relatively to each other that in assembling the parts or utting them together they Will it very close y and tightly and will have to be forced into position under considerable pressure in a suitable device.

It will be understood that the details of construction of my improvements may be varied, if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is`

1. A metal roller or Wheel having a Hat tread and' comprising a metal tire or rim aving on each edge an inwar y-ex en g annular lip or flange, tWo ball-cu holders', each having an annular lp or ange extending at right angles to the rnan portion thereof and of a Width a little less than one-half the Width of the rirn, and fitting' tightly Within the rim, and each havin a central hub portion, and a ball-cu tt within each central hub portion an secure therein.

2. A metal roller or Wheel having a flat tread, and consisting of a metal tire or rim, tWo ball-cup holders, each having an annular lip or flange extending at right angles to the main ortion and of a width a little less than onealf the Width of the rim, and extending Within the rim and secured therein by the turned-over edges of the rim, and each having a central hub portion, and two ballcups, each extending Within the central hub -portion of a ball-cup holder, and secured therein.

3. A metal roller or Wheel having a flat tread), ililnd ccpslisting of la 1rlnetal tire or rin, two a -cu o ers, eac avin an annu ar lip ori-Bangr'heeon extending gat right anges to the main ortion, and extending Within said rim, and) secured therein by the turned-over edges of the rim, and each ballcup holder having a hub portion, and two ball-cups, each extending Within a hub portion, and secured therein by a portion ofthe hub extending into a notch on the edge ofthe ball-cup.
